Okay, www.ecosia.org is a search engine that works to save the rainforests. Basically, every time a person searches with it and then clicks on one of the sponsoring links, the sponsoring links donate money to the site, which uses it to protect rainforests :). This will explain better http://www.ecosia.org/how.php .

I'm not sure how interested you guys are, but if you could use the site (and click on sponsoring links) and/or tell other people, that'd be great. Oh, and if you install it, it becomes the search engine on your adress bar to make using it a bit quicker. :)
